最近在Ubuntu上安装LAMP，并假设Wordpress。发现权限无论怎么设，除非设置为执行Apache的用户，才能避开这个问题。

弄了半天，最后发现在wp-config.php里面加入这句话可以解决这个问题：

define('FS_METHOD', 'direct');

在安装完Win10以后，才发现居然没有打开硬盘的AHCI模式。怎么办？

别急，其实很简单。不用重装Win10的。照下面步骤来就行。

  1. 管理员权限打开命令提示符
  2. 使用这个命令打开启动自动进入安全模式： 
    bcdedit /set {current} safeboot minimal
  3. 重启电脑进入BIOS
  4. 更改硬盘工作模式为AHCI，保存退出
  5. Win10会以安全模式启动
  6. 在安全模式下用管理员权限打开命令提示符窗口
  7. 执行如下命令关闭启动自动进入安全模式 
    bcdedit /deletevalue {current} safeboot
  8. 重启电脑以正常模式进入Win10
  9. Duang～成功！

如下命令

grep -rnw '/path/to/somewhere/' -e "pattern"

-r 或者 -R 为递归查找, -n 是行号 -w 为要求全匹配. -l (小写L) 参数可以只列出文件名.

除此以外, –exclude 或者 –include 参数可以提供更有效的查找。比如:

grep --include=\*.{c,h} -rnw '/path/to/somewhere/' -e "pattern"

这个可以查找扩展名为.c或者.h的文件. –exclude的用法也类似：

grep --exclude=*.o -rnw '/path/to/somewhere/' -e "pattern"

上面这行命令在搜索中会排除扩展名为.0的文件。和包含/不包含文件一样，目录也可以使用 –exclude-dir 和 –include-dir 参数。 比如下面列出怎么使用 –exclude-dir:

grep --exclude-dir={dir1,dir2,*.dst} -rnw '/path/to/somewhere/' -e "pattern"

如果单是遍历查找文件的话可以用

find . -name '*.xml'

如果想遍历删除某种类型的文件的话，可以用

 find . -name '*.xml' -type f -delete

很多喜欢Win7,Win8的朋友正在经受着整天提示升级Win10的骚扰。就是不升，怎么着～哈哈

那怎样去掉这个恼人的提示呢？

卸载KB3035583，然后选择忽略此更新。

Done

If you are using a wired connection on your PC or using a USB connection with your 3G or 4G LTE dongle, you can share this connection to other devices. This means you can connect other smartphones, tablets and even laptops to this connection by creating aportable wireless hotspot on Windows 10. There is no direct UI to create the hotspot, but you can easily do it using few commands.

In this article, we will show you how to get started in creating a wireless hotspot in Windows 10.

To get started, right click on the Windows start button and click Command prompt (admin). This will open the command prompt in administrator mode.

Now type the following command;

netsh wlan set hostednetwork mode=allow ssid=AdHoc key=password

In the above command, you can add your own value for SSID and enter your key. Now press enter.

Now to start the network, type the below command;

netsh wlan start hostednetwork

Now that ad-hoc connection is created with passkey, you need to share the existing connection.

Once the hosted network is enabled, you can see MyWiFi connection listed in the network and sharing center. Now the network needs an internet connection and for this, you need to share the existing active Internet connection. Right click on your existing internet connection and select properties.

Now select the Sharing tab in properties. Check the box against “Allow other network users to connect through this computer’s internet connection”. Then select the newly created Wi-fi connection from the drop down list. Now save the details and close the properties.

Now you can see Internet available on the new hotspot connection created.

In case you want to stop the hosted network, use this command;

netsh wlan stop hostednetwork

If you find this method difficult, you can probably use tools like Virtual Hotspot,Connectify or mHotspot.

发动机灯亮了，经检查是引擎在冷车启动的时候有哑火现象。

网上研究了一下，决定添加Sea Foam试试，说可以非常有效的清除积碳。驾驶时是有改善，但是还是没能解决冷车哑火问题。去Dealer处检测说是进气门积碳，需要打开引擎盖手工清理，报价$1xxx。当然就果断让他去S。出来找了个修理厂说是可能点火线圈和火花塞老化了，要求换。好吧，换！但是…问题依旧！老板没辙，说可以试一试44k，说比Sea Foam好。好吧，试就试吧。结果呢，灯还亮！无言… 网上搜了搜，找了一家比较靠谱的专修德国车的地方，检测以后说可以试一试大众的厂家添加剂G 001 780 M3，说积碳问题大部分车在用了这个以后就可以解决。好吧！加吧～ 但是结果还是一样，灯照常亮！没法，只有打开发动机盖看了。打开的结果:进气门积碳很少，但是燃油喷嘴堵塞严重(图一)。只有更换～ 经这个维修点的经验人士介绍，带T的发动机时间长了基本都有这个问题，BMW的还更严重些。[流汗][流汗][流汗] 折腾啊！
